4 dBi N-Male Helium Hotspot Fiberglass Outdoor Antenna & Bracket Mount for RAK, Bobcat, Nebra, SenseCAP


Pickup available at 2251 NW 41st Street

Usually ready in 1 hour

This is an outdoor fiberglass encased omni-directional 915 MHz N-Male antenna with 4 dBi gain. Also included is an outdoor bracket designed for mounting to a pole or PVC pipe. THIS DOES NOT INCLUDE THE RAK MINER ITSELF.

This antenna is compatible with the RAK V2, Bobcat 300, Nebra Indoor, SenseCAP M1, Kerlink, Linxdot,, Helium Hotspot, Kerlink, FreedomFi & LongAP, (915 MHz USA and Australia versions + Europe 868 MHz also) but requires an RP-SMA male to N-female coaxial cable to fit, and we carry compatible coaxial cables. This has the same gain as the Bobcat factory antenna and would be a better choice for RAK or Nebra owners.

We do recommend RokTape to seal all outdoor connection points.

Or our Indoor version of this antenna: Rokland 4 dBi antenna with RAK Magnet Base

Beware cautious of gain inflation- some places arbitrarily inflate antenna gain numbers to appear better than competing products. Because gain cannot be easily measured by the end users, we have seen similar antennas marketed as numbers like 18 dBi to 30 dBi that are not even 20 inches tall. Rokland has been making antennas for over 14 years for WiFi, 4G, and other applications. Our 915 MHz antennas are listed with actual specifications. You also do not want extremely high gain as your path will be very narrow and miss other hotspots.

I see similar looking antennas online that say for 600 MHz to 2700 MHz, is a wider frequency spectrum better? 
Antennas with a focused spectrum will have better performance on that band segment vs antennas with a very wide spectrum. We would not recommend using antennas that are also WiFi 2.4 GHz compatible with your mining equipment. This antenna has a frequency range of just 698-960 MHz to give you maximum performance.

Need a low loss shielded cable?
This requires an RP-SMA male to N-female coaxial cable to fit your miner, and we carry compatible coaxial cables.

Recommended Use
Use with your Helium miner to help increase your coverage area. This antenna can be used outdoors and is weather and dust-proof.

Compatible with:

Bobcat 300
Nebra Indoor/Outdoor
SenseCAP M1
Helium Hotspot

Bought 2 antennas, both are >2.0 swr at 915

I bought two antennas, both are tuned for 878mhz, at 915 where LORA and Helium are at the SWR is > 2.5:1 making them useless.

Thank you for your feedback. In our Agilent testing the VSWR was at or below 2.0. Our team has reached out to you today to discuss test equipment and see if replacement is necessary. The antennas are tuned betweened 698 and 960 Mhz so performance should be good at both 878 and 915.

Amazing customer service

This is an update to a review I had left before. I had left a 1 star as the antenna was not working. I was contacted immediately and offered solutions to resolve the faulty antenna. They immediately sent out a new one that should be here today. I am leaving a 5 star review whether the new antenna works or not as I am greatful to see such amazing customer service! It is rare these days and I know they will make any issues I have right.

Awesome outdoor Helium antenna

This is an awesome antenna: not too tall but still performs really well. It works perfectly with the RAK Wireless SenseCAP M1 Outdoor Enclosure Kit, since you can connect the antenna directly to the enclosure without any adapters or cables reducing the signal.

4 dBi N-Male Helium Hotspot Fiberglass Outdoor Antenna & Bracket Mount for RAK, Bobcat, Nebra, SenseCAP

Recomended 100% Good service is not often seen.

Excellent service, I had ordered an antenna, cable and lightning insulator that were mistakenly incompatible and they called me to confirm and select the correct one. Today such a service is not often seen. Also everything arrived 3 days earlier than expected. I recommend them 100%.
